NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).
I've been trying to get the Nvidia driver working for my laptop for months and have had no luck. I have a Sony Z Series with an Nvidia GT 330M in it. The only drivers that are available for it are the proprietary drivers from Nvidia so I installed it, configured the xorg.conf and I'm still getting errors. This is what I get when I run 'startx'

Code:
[root@localhost X11]# startx

I got this xorg.conf by having the system configure it for me with 'X -configure' i think it was, then I added the EDID part because I guess these Sony laptops changed the chipsets a little from the actual driver (from what I read). Any help on this would be greatly appreciated, thank you!!

Re: NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).
There is one thing that is very noticeable. There is a line missing in your /etc/X11/xorg.conf file.

The "Files" section should look like this:

Code:
Section "Files"
	ModulePath   "/usr/lib64/xorg/modules/extensions/nvidia"
	ModulePath   "/usr/lib64/xorg/modules"

But also that xorg.conf file looks all wacked up.

Try copying that file to a backup, like /etc/X11/xorg.bak then delete /etc/X11/xorg.conf

After doing that, tun nvidia-xconfig and have it create you a new /etc/X11/xorg.conf file.

Re: NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).
i tried changing the file section to what you said and still the same messages. this is the xorg.conf that the nvidia installer creates for me:

Code:

which also gives me the same error messages. is there possibly a way to check the status of the video card /dev/nvidia0 to see if its busy with something else?

Re: NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).
you can see what video devices you have and what (if any) kernel modules are in use for them.

Code:
lspci -k

Re: NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).
amongst other things, this is what lspci -k gives me:

Code:
01:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce GT 330M] (rev a2)
	Subsystem: Sony Corporation Device 905a
	Kernel driver in use: nvidia
	Kernel modules: nvidia, nouveau, nvidiafb
so does this mean that nouveau is using my video card? that would explain why the nvidia driver cant access it.

i don't that nouveau should be running though cause its blacklisted in my kernel arguments in my grub.conf

Code:
kernel /vmlinuz-2.6.35.11-83.fc14.x86_64 ro root=/dev/mapper/VolGroup-lv_root rd_LVM_LV=VolGroup/lv_root rd_MD_UUID=5a14b37d:e612976d:a210e54c:93c35ea5 rd_MD_UUID=4e4e1669:14893587:c5793d26:40b61cd5 rd_LVM_LV=VolGroup/lv_swap rd_NO_LUKS rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us nomodeset rhgb quiet nouveau.modeset=0 rdblacklist=nouveau

Re: NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).
that just tells you the kernel modules that are on your system for that device. it is using the nvidia driver, but you have noveau and nvidiafb that can be used, but aren't.

That looks like the nvidia kernel module is getting use of your video card, so it's being loaded and nothing else is grabbing it.

From looking at your /etc/X11/xorg.conf file, it is showing 2 video cards.
1 on PCI:01:00:00 (which is shown above in the lspci -k output), and another on PCI:0:2:0. What is that second card you have the definition for in your xorg.conf file?

it shows up in the xorg.0.log you posted above as well..

Re: NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).
oooooo ok, that makes sense.

the second card is a low end intel gpu. this laptop has one of those hybrid gpu switches between the intel and the nvidia card. ive read that theyre a real pain in the ass under linux as of now. i dont really care about being able to swap between the gpus at this point i just want one of them to work with my 1920x1080 display. which i guess brings up the point, could my nvidia gpu not be loading properly because im using my intel gpu?

Re: NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).
there is a setting in the BIOS that lets you select which video adapter to use. Go into your system BIOS and select the nvidia video.

Then take out the entries for the second adapter from your /etc/X11/xorg.conf file.
(actually, you may want to take these out first, shut down, change your BIOS and then reboot)

try making your /etc/X11/xorg.conf file look something like this:

Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig

You can also just remove the /etc/X11/xorg.conf file and run nvidia-xconfig again after you make the changes to the BIOS.

It looks like support for those GPU's is coming, but just not quite finished yet. There are some upstream kernel's that have some support for them in it, just not an F14 kernel yet.

Re: NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).
thats a problems though, there is no choice to select between GPUs in the bios. ive check and read on the internet that ppl have had to flash their bios to a custom image in order to do so which i would really like to stay away from.

so i might be able to get a better resolution if i installed the drivers for the intel gpu...ill try that.

thats good to know, because what i was reading made it sound like it was never coming lol

I really don't have any experience with that wacked out set up Lol

But, I did find a note in the F14 common bugs that says that currently a workaround is to use the vesa driver, although that wouldn't give you the results you are wanting.

sure can.. here is the link, and there is also a link there to a bugzilla bug.

http://fedoraproject.org/wiki/Common...s#edp_problems

and here is where it shows how to use the vesa driver

Re: NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).
possibly someone else can jump in and give you a few tips, too.

I sure hope you can figure it out and get things working for you, though.
